"Flagship dual-GPU 4870 X2 cards will include 2048 GB of GDDR5 memory clocked at 1.73 GHz."

Should read either 2GB or 2048MB. Although a 2 Terabyte GDDR5 card would sure be nice.

i'm not very good when it comes to this. so if I were to get a new card(i currently have an old 7900 GTX) which would card right now would be the best if i were only to buy one?

Greetings crawlgsx, the error was noted and corrected. Thanks for the feedback.

RE J.D =): Hi John, when it comes to getting a new card, it all depends on what kind of financial strain you can bear. In general, 1GB of memory did not prove to be such a significant advantage over 512MB, but time is passing by and new titles will be more demanding. 4850 512MB GDDR5 sounds like a good catch, since price difference to 1024MB model. It might be a good idea to wait for overclocked versions of the cards.

We'll keep an eye on real deals.

Stay tuned,

Theo

Lets hope it beats the pants off the 9800 gtx and nvidia gets their crap in order and puts out the gt200.

Why are so many cards being offerred with different amounts and types of memory?
Also what happened to GDDR4?

GDDR3 is simply cheaper than GDDR4. Even though GDDR4 is more power efficient and will clock higher in raw price it simply doesn't compare to old faithful.

Now i am wondering the % of Power used by Memory itself.

And If the card can do some serious power saving when idle i think ATI is back in the game. As they have been usually good on the Mobile front.

John, it's more like, how much do you want to spend? If you want the down right best period, get two of the 4870 X2's when then hit the stores and Crossfire them. But that's $1000. The 4850 256M GDDR3 for $229 should be below $200 in a couple weeks after release, unless it's as good as they say it will be, then it will sell like hot cakes and go up in price. But that cheaper card will most likely be the target for 99% of the games made.

I cannot see the picture; was it removed?

Regarding achieving performance/watt ratio or power efficieny, is there a sweet spot with clock frequency combination setting of the shader clock and the core clock?

I wonder to what extend these ATI cards can overclock the shader unit and if there will be software.

GDDR5 with much higher throughput and much lower power consumption is very much a sweet spot!

heheh
when i first saw the picture, i thought: "i wonder if that's an RV770.... blaahh, yeah right!"

nice! :o)

Ok, yes....I definitly want one.
The Q however is if i should buy the 4870 W/ 1 Gig
or the 4870 x2, overclock it, and hope it has a gig rather than 512 x2 (like its predecessor)
((3870 x2))
I guess the 512 x2 wouldnt be an issue if they have a perfected integrated memory controller built into the Gpus, or between them.
Yes I game on my tv's native resolution @1920/1080.

That depends on how well amd/ati will support the x2s dual gpu crossfire option. I guess you could use the 3870 x2 as a template

Come on, the picture was originated from Chinese website. And I can tell you that it is a Photoshopped work. Period.

Anything else? I can tell you that GDDR5 version of RV770 will be out TWO months after the GDDR3 version. And RV770 Pro will be out first.

Heya I, picture originates from Tom's Hardware database. If our database is wrong, so be it. All I know is that RV770 board I saw (but was not allowed to take pic of) had interesting number of connectors. We used to have three connectors: DVI D-SUB TV or 2xDVI TV. Now, we're heading into multiple connector era. I only wonder how many outputs will actually RV770 support at the same time.

Lol... I just picked up a HD3870x2... Its pretty sweet, but I was unaware of the Low filter rate problem mentioned in the article. The chip is performing pretty good, but I get the feeling that its not doing as well as it can... In the sense, that I get pathetic speeds with 3Dmark 06... Correct me if I'm wrong, but shouldn't a top of the line card be worth something in 3Dmark 06?

What's the difference in terms of performance between the 3870x2 and the 4870x2?

Way to go ATI!

AMD/ATI count each individual processor in those 480 stream processors.

Nvidia count his processors un groups of 4 (each one for: red, black, green, and alpha transparency), so, by NVIDIA accounting, ATI have 480/4=120 processors, or, by ATI accounting, a nvidia 8800 GTX have 128*4=512 processors.

Garr! You're so wrong there mm! So wrong! Ati and Nvidia don't use the same shader system, go read bro!

Well, I suppose AMD will put at least one DVI and maybe two DisplayPorts, there is also a possibility that one HDMI with one DisplayPort will be supported. But this is high-end.

Then I suppose one dual-link DVI two DisplayPort one S-Video maybe is the combination on RV770 XT.
